In the adjoining figure, SS is a spherical surface separating two media of refractive indices n 1 and n 2 where n 1 > n 2. C is the centre of curvature of the spherical surface. An observer, keeping his eye beyond C in the medium of refractive index n 2 views the refracted image of an object AB placed as shown in the medium of refractive index Thin Lens Equation. A common Gaussian form of the lens equation is shown below. This is the form used in most introductory textbooks. A form using the Cartesian sign convention is often used in more advanced texts because of advantages with multiple-lens вЂ¦

Unlike idealized thin lenses, real lenses have a finite thickness between their two surfaces of curvature. An ideal thin lens with two surfaces of equal curvature would have zero optical power, meaning that it would neither converge nor diverge light. A lens whose thickness is not negligible is called a thick lens. In this case, we can not Refraction at a spherical surface .

If the light ray hits an interface from within the lens at an angle of incidence that exceeds the critical angle *, the light ray reflects off of the surface rather than passing through.

Unlike idealized thin lenses, real lenses have a finite thickness between their two surfaces of curvature. An ideal thin lens with two surfaces of equal curvature would have zero optical power, meaning that it would neither converge nor diverge light. A lens whose thickness is not negligible is called a thick lens. In this case, we can not REFRACTION AT A SPHERICAL SURFACE. As we mentioned in Section 35-2, images can be formed by refraction as well as by reflection. To begin with, letвЂ™s consider refraction at a spherical surface, that is, at a peripheral interface between two optical materials with different indexes of refraction.

Lenses One practical application of refraction is in lenses. There are many parallels between how lenses work and how spherical mirrors work. For one thing, the same equations apply, which is rather surprising. f is the focal length of the lens, (with an appropriate sign вЂ“ see below).
